Create AWS Lambda from CloudFormation

假設已準備好 yaml file，內容如下：

AWSTemplateFormatVersion: '2010-09-09'
Description: 'AWS CloudFormation Sample: AWS Lambda Function with Python.'

Resources:
  HelloWorldFunction:
    Type: 'AWS::Lambda::Function'
    Properties:
      Handler: index.lambda_handler
      Role: !GetAtt LambdaExecutionRole.Arn
      Runtime: python3.8
      Code:
        ZipFile: |
          def lambda_handler(event, context):
              return {
                  'statusCode': 200,
                  'body': 'Hello, World!'
              }
      Timeout: 5

  LambdaExecutionRole:
    Type: 'AWS::IAM::Role'
    Properties:
      AssumeRolePolicyDocument:
        Version: '2012-10-17'
        Statement:
          - Effect: Allow
            Principal:
              Service: lambda.amazonaws.com
            Action: 'sts:AssumeRole'
      Policies:
        - PolicyName: 'lambda-basic-execution'
          PolicyDocument:
            Version: '2012-10-17'
            Statement:
              - Effect: Allow

                  - 'logs:CreateLogStream'
                  - 'logs:PutLogEvents'
                Resource: 'arn:aws:logs:*:*:*'
